$PECIPICATION forming part of Letters Patent l lo. 357,713, dated February 15, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, Gnonen F. Humor-tins, a citizen of the United States, residing at \Von cester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Protective Attachments for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

Hy invention relates to looms and to an attachment or protective mechanism to be ap plied to looms of any usual and well-known construction, to act, in connection with the or dinary protecting mechanism, to stop the loom when the lay is on the backward stroke, in the case of a shuttle remaining in the shuttlebox when it should be thrown through the warp, and in which case the loom would not be stopped by the ordinary protecting mechanism.

It frequently happens that by reason of the breaking or catching of a picker a shuttle will not be thrown as desired, but will remain in the shuttle-box, in which case it is very desirable to have the loom automatically stopped when the lay is on its backward stroke, for if the loom continues to operate and the lay heats up with a shuttle remaining in its box, as above set forth, serious breakage of the warp is liable to occur before the loom will be stopped. It will he understood that this trouble is liable I to occur in looms using several shuttles when,

for any reason, one shuttle fails to leave its box at the proper time, so that the shuttle coming from the other side of the loom, not being able to enter the occupied box, will remain in the shed, and thus when the lay returns at the rip-beat the latter shuttle will cause breakage of the warp-threads.

This is the object of my present invention, to wit: to automatically act upon the shipping mechanism and stop the loom upon the bac ward stroke of the lay, in case of a shuttle remaining wholly or partly in its box, when it should be thrown through the warp; and this object I attain by means of the mechanism illustrated in the drawings, and to be hereinafter described, which is applied to and used in connection with the ordinary protecting and shipping mechanism of usual construe tion, adapted to automatically stop the loom as the lay heats up in case the shuttle, as it is thrown across, fails to enter the reeeivingbox a sufficient distance to throw 0d said protecting mechanism.

I have shownin the drawings adetached portion of awell-known form of drop-box loom provided with the usual protecting mechanism for operating one form of shipping mechanism with my invention applied thereto, and sufficiently illustrated to enable those skilled in the art to which my invention belongs to understand the construction and operation thereof.

Referring to the drawings, Figure 1 represents a vertical crosssection of a detached portion ofa weltknown form of drop-box loom, showing the ordinary protecting mechanism and a portion of the shipping mechanism and my supplemental. attachment or protecting mechanism applied thereto, as will be hereinafter fully described; and Figs. 2 and 3 repre sent a side view and a plan view, respectively, of a connecting device or hook, forming a part of the supplemental protecting mechanism, as shown in the drawings.

The manner of construction and mode of operation of the usual protecting mechanism shown in the drawings for automatically stopping the loom upon the forward stroke of the lay, in case a shuttle remains in the warp or does not enter its receiving-box a sufficient distance to throw off said protecting mechanism, are old and well known, and therefore require no detailed description, as my present invention simply consists of an attachment or mechanism applied to said protecting mechanism and operated in connection therewith to stop the loom upon the backward stroke of the lay in case a shuttle remains in the'shuttle-box when it should be thrown through the warp.

In the accompanying drawings, the part markedp is the lay of the loom.

7c is the protector-rod, supported and turning in brackets or supports k, secured to said lay p in the usual manner.

IOO

n is the finger, 0 the binder, and j the dagger, constructed in the usual manner and forming a part of the ordinary protecting mech-" anism.

The part marked i is the breast-beam.

Z is the knock-off lever, supported under the breast-beami and connected with the shipper handle 10 in the usual manner, to be acted upon by the dagger j at the proper time to move forward said shipper-handle w and turn the shipper-shaft b and ship the driving mechanism of the loom, through the shipper-arm r, lock-lever s, and shipper-rod 25, connected with mechanism for throwing the driving-belt out of action, all in the usual and well-known manner.

Ihave not shown in the drawings the beltshipping mechanism connected with the rod t, as the same is old and well known, and is fully illustrated and described in my previous application for a patent filed May 24, 1886, Serial No. 203,059.

My supplemental protecting mechanism or attachment is designed to be applied to the ordinary protecting mechanism, and preferably to the dagger j, and connected, either directly or through intervening mechanism, with the shipper-shaft Z) or the shipping mechanism of the loom, so as to operate the same and automatically stop the loom upon the backward stroke of the lay in case of a shuttle remaining in its box when it should be thrown through the warp, and when the loom would not be stopped by the ordinary protecting mechanism.

I have shown in the drawings one way of connecting the attachment m, secured upon the daggerj, with the shipper-shaftb to operate the same at the proper time; but I do not limit myself to the connecting mechanism shown, for any equivalent mechanism, or any equivalent way of connecting saiddevice with the shipper-shaft b or the shipping mechanism to operate the same and stop the loom upon the backward stroke of the lay, may be employed in lieu of that shown.

The attachment or catch m is secured to the under side of the dagger j in this instance by a bolt, 12. If preferred, the catch on may be made a part of and integral with the dagger j. The catch at is in this instance connected with the shipper-shaft b to operate the same at the proper time by means of the device or hook at, which may be made in substantially the form shown and supported at one end upon the shaft 2), which passes through the oblong slot 0, said slot allowing the hook a to move back and forth upon the shaft b and the shaft to turn within said slot 0.

A bracket or angle support, 71, secured to the breast-beam z', supports the outer end of the hook c, as shown in Fig. 1, allowing of a backward and forward motion of said hook.

Upon the shipper-shaft b is secured, to turn with said shaft, an arm, f, provided with a pin, 0, extending out at right angles therefrom. The arm f is in this instance located between the main body of the hook a and the curved projecting arm 9, formed on one side thereof, and prevents any sidewise motion of the hook at upon the shaft 1); but it will be understood that any well -known means of preventing sidewise motion of the hook it may be employed in lieu of that shown, if preferred, and the hook to may be madewithout the projecting arm 9.

A projection, (1, extends up from the body of the hook at at its inner end, and is in contact with the pin 6 on the arm f, to turn or move rearward said arm at the proper time, and at the same time to turn the shipper-shaft b and operate the shipping mechanism to stop the loom.

The operation of my attachment or supplementary protecting mechanism, as shown in the drawings, will be readily understood by those skilled in the art from the above description, in connection with the drawings, and is as follows:

On the backward stroke of the lay p, if the shuttle a, which should have been thrown through the warp, still remains in the shuttleboX, the finger a will remain held out by the binder 0, and the end of the daggerj will be depressed or thrown downward into the position shown in Fig. 1. At a certain position of the lay 19 upon its backward stroke the catch an, attached to the dagger j, will, under the circumstances above described, catch on the projection g of the hook a and pull said hook in the direction of the lay p. The pulling of the hook at will cause the projection d, bearing against the pin 6 on the arm f, to draw over said arm and turn the shipper-shaft I) sufficiently far to throw the shipper-arm '1' out of the locking action of the lock-lever s,

when the driving-belt of the loom will be thrown out of action by the shipper-rod t, in any usual and well-known manner,and as fully illustrated and described in my application for a patent above referred to, and the loom will be thus automatically stopped upon the backward stroke of the lay. The handle 20 is drawn forward in the usual manner by the turning of the shipper-shaft b, and when said handle 10 is drawn back into its first position to start up the loom the shipper-shaft b and the arm f, secured thereon, will also be turned back into their first position, and the pin 6 on said arm f, pressing against the projection d of the hook a, will also draw the hook aback into its original position, ready to be acted upon again at the proper time by the catch m. I prefer to attach my catch m, or equivalent device, to the dagger j, as above described and shown; but it will be readily understood by those skilled in the art that it can equally well be attached to the finger n, and arranged to connect with the shipper-shaft b or the shipping mechanism to operate the same, or it can be attached directly to the protector-rod k.

The value of my invention will be fully appreeiated by those skilled in the art. It is simplein construction and operation, not liable ICC IIO

to get out of order, and can be easily adapted and applied to any of the ordinary forms of looms which are provided with the ordinary protecting mechanism,consisting of the binder 0, finger n, dagger j, and protector-rod k, for operating automatically the shipping mechanism.

It will be understood that in case the shuttle a does not remain in the shuttle-box, but is thrown through the warp, then the finger n will not be held out by the binder o, and the dagger j will not be depressed, as shown in the drawings, upon the backward stroke of the lay, but said dagger will be raised by means of a spring secured to the rod 70 in the usual manner, and prevent the catch m from coming in contact with the projection g of the hook to or hitting said hook, allowing said catch m to pass freely over the same and the loom to continue to operate.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the breast-beam and the shipper-shaft b, the shipper-rod t, and connections between said shaft and rod, of the lay, the protecting mechanism carried by the latter, a hook, a, adapted to turn the said shaft b when required, and a catch, m, carried by the said protecting mechanism and adapted to engage the said hook as the lay beats back, to operate the said shipper-shaft and thereby stop the loom, substantially as set forth.

2. The combination, with the breast-beam, the shipper-shaft I), having arm f, the shipper-rod 15, connections between said shaft and rod, the lay, the finger a, the protector-rod k, and the dagger of the catch secured to the said dagger and the hook at, having the projection d, for engagement with the said arm f, and the proj eetion g,to be engaged by the said catch m, substantially as set forth.
